SAJEEJIY ZONE AND MARKER FUR THE SAME.

Application led April 29,

4To all w/mm it may concern:

Be it known that wepGEoIIGE C. KIMMEL and HERMAN BILLING, citizens of the United States, residing at'Cincinnati, in the county of Hamilton and State of Ohio, have jointly invented certain new and useful Improvements in Safety Zones and Markers for the Same. of which the following is a specification.

It is the object of our invention to provide' new and useful safety zones and markers for the same of permanent character, which are arranged to be imbedded in the street or roadway. so as to becornea permanent part of the same; further. to provide safety zone markers which are a permanent part of the street or roadway, and lso constructed and arranged that the samefareV not effaced byv travel thereover: further; to provide novel safety zone markers provided with novel means for fixing the same in the street or roadwa)v and with novel means to assure the visibiliti7 throughout travel thereover: and, further, to provide a safety zone marker of novel construction and arrangement.

The invention will be further readily un .derstood from the following description and claims. and from the drawings, in which latter:

Fig. 1 is a plan view of a section of a street having our invention applied thereto.

Fig. 2 is a plan view of one of' the blocks of our improved device.

Fig. 3 is a central longitudinal vertical section ot' the same, taken on the line 3-3 of Fig. 2.

Fig. 4 is a plan view of the base of the same. I

Fig. 5 is a horizontal section of the saine taken in the plane of the line 5,-5 of Fig. 6.

22, in which our improved device. is imbedded. The roadway is exemplified as comprising street car-tracks 24. 25. having rails 26. the arrows showing the directions of travel along the tracks. Our improved device is exemplified as marking oft' safety zones 27, 28., and safety crossing zones29, ao, 31 and 3 I.

nr improved device preferably comprises blocks which preferably comprise a base 3G. and an insert 3T. the insert forming the marking portion of the device. The base is formed by a suitable traine-resistant material, for instance cast-iron. and the marking insert is preferably composed of a distinguishing material, which is also trafficresistant. and may be an alloy. which will have an appearance readily' distinguished from the surface of the adjacent roadway. This appearance ma)- he bright or white` or 7B -We prefer to malte the distinguishing strip of a white metal alloy, containing for instance aluminum. tin. zinc or other material imparting a distinctive appearance. Preferably the `side margins or walls of the base as well as the inserts are of materials contrasting in appearance or color from ea'ch other and the surface of the roadway. Travel of auto tires polishesthe inserts.

lVe prefer to unite the base and the insert in such a way as to form a firm union between them. The base may, for instance, be first formed and then the insert inserted. ll'e prefer to form the base with a recess 41, 90 extending lengthwise thereof, into which the insert may.7 be poured after the formation of the base. We prefer to provide the base with a lengthwise groove 43. having overhanging side walls 44. into which the Inaterial of the insert extends -for forming a.

' tongue 45 extending lengthwise of the insert which is located in the lengthwise extending groove in the base for holding the insert downwardly firmly upon the base. lVe prefer to maire this groove contracting in opposite directions toward the ends of the base,

as exemplified at 42. the tongue being correspondingly contracting toward its ends.

The recess is at each of its sides provided 10i with an upwardly and outwardly sloping wall 41S. from which an upright wall i9 of the base extends upwardly. the insert having corresponding reverse walls matching therewith so as to provide a substantial ing. A firm connection between the insert and the base is provided by providing a flow 15T-of metal lengthwise of the recess toward both f its ends from the middle of the length of the recess, so as to laterally fill the space between the side walls of the groove and of the recess. Suitable means are provided at the ends of the recess, as by means of dams across the resiective ends of the recess, to limit the en wise flow of the metal of the insert. This dam ma be so placed and arranged that the i metal o the insert, when cast, will extend slightly beyond the ends 51, 52, of the base, the overhanging ends of the insert being trimmed in line with said ends after the same has been cast.

One end of each of the bases is provided with a tongue 54. and the other end with a groove 55, these tongues and grooves being shown extending horizontally across the widths of the blocks. The tongue is referably of smaller cross-section in heig it and length than the groove, and the space between the tongue and the walls of theI groove is preferably filled by a binder 56, when the markers of our improved device are put in lace. This binder may be the material of which the roadway or its foundation is composed, for instance cement or concrete, exemplified at 57, or asphalt, or other mate ria. Binders 58, 59, are located between the rails and the roximate ends of the markers, these bin ers extending into the grooves or about the tongues at thev ends of the markers and into the recess at the sides of the rails to firmlywhold the blocks in place.

The sides of the base are preferably provided wth depressions 61, forming ribs 62, between them. The materials of which the road way is com is received in these recesses, so that the material of the roadway, for instance cement or concrete, or other material, forms a union with the marker, in order to hold the same in the roadway.

Our improved markers are so constructed as to readily adapt themselves to curva-tures for forming rounded ends or corners for the Imarkings of the safety zones, for instance, as shown by rounded corners 63, 64. Curved blocks 65 are exemplified in Figs. 9 and 10, the parts thereofbeng indicated by similar but primed reference numerals. The ribs and the parts thereof are formed, as shown by the r1bs` (32 and the depressions Gl.' so that the patterns for molding the same may be readily drawn out of the sand, for instance in the direction of the dotted line G6.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is:

1. A safety zone marker comprising a base and an insert at the top of said base, said base provided with connecting means between them, the said connecting means contracting in width towards the ends of said safety zone marker.

2. A safety zone marker comprising a base and an insert at the top of said base having overlapping connecting parts hetween them at the respective sides of said Safety zone marker, and the respective ends of said base between said overlapping connecting parts provided with oppositely formed complemental connecting parts integral with said base to connect the proximate ends of endwise arranged markers.

3. A safety zone marker con'iprising a base and an insert of distinguishing appearance at the top of said base, the said base provided with a depression extending lengthwise thereof in which said insert is received and the bottom of said insert and the bottom wall of said depression provided with a mating tongue and groove provided with overhanging side walls extending lengthwise of said depression at the respective sides of said safety zone marker, and the respective ends of said base between said over-hanging side walls provided with oppositely formed complemental connecting parts integral with said base to connect the proximate ends of endwise arranged markers.

4. A safety zone marker comprising a base the top whereof is provided with a recess extending lengthwise of said marker,

and an insert received in said recess. the top of said insert and the tops of the side walls of said recess being4 at substantially the same level and of contrasting appearances, and the bottom of said insert and the bottom wall of said recess provided with a mgting overlapping tongue and groove which contract toward the respective ends of said base.

5. Safety zone markers arranged to be imbedded in a roadway respectively comprising a base, and a part of distinguishing appearance at the top of said base, the ends of said base provided respectively with a tongue, and a groove of greater cross-sectional area than said tongue, the tongues anrl grooves at the proximate ends of proximate markers arranged end-to-end mating each other with a space between said tongue and the walls of said groove, the sides of said.

base provided. with depressions, and the binmn material of the roadway received in sai spaces and in said depressions to hold said markers in said roadway;

1 6. A safety zone comprising straight Vfharkers and vcurved malkers, said curved -lnarkers forming the roundings in the corners of saidsafety zone, the proximateends of said straight m'arkers and of said curved markers provided with com plernental tongues lo and grooves, and inserts in the tops of said respective markers, the said inserts and said straightmarkers and curved markers provided wth complernentul interenguging faces which contract in width towards euch of the ends of said respective markers.

` In testimony whereof, we have hereunto signed our names in the presence of twosubscribing witnesses.
